Directions

Heat oil in a medium saucepan over medium-high heat. Add thyme and cook 30 to 60 seconds until fragrant. Add diced tomatoes and tomato sauce. Bring to a boil. Reduce heat to medium-low and cook, uncovered, 5 to 10 minutes or until sauce thickens slightly.

Combine ricotta and spinach in a bowl.

Spread 1/4 cup tomatoes evenly on the bottom of a 9x9-inch baking dish. Place one tortilla over tomatoes. Spread 1/3 of ricotta mixture over tortilla. Top with 1/3 of chicken, 1/4 of cheese and 1/2 cup tomatoes. Repeat layers two more times, ending with the fourth tortilla on top. Press lightly before spreading remaining 1 cup sauce evenly over top.
